 	<h1>0.6.0-incubating Released</h1>

 	<p>The latest Apache Aurora release, 0.6.0-incubating, is now available for download. This version marks the second Aurora release since becoming part of the <a href="http://incubator.apache.org">Apache Incubator</a>, and includes the following features and improvements:</p>

 <ul>
 <li>Introduced highly-available, scheduler-driven job updates in beta (<a href="https://issues.apache.org/jira/browse/AURORA-610">AURORA-610</a>)</li>
 <li>Improvements to the Aurora web UI, including visualization of job updates</li>
 <li>Added automatic service registration in ZooKeeper (<a href="https://issues.apache.org/jira/browse/AURORA-587">AURORA-587</a>)</li>
 <li>Updates to Aurora client version two, deprecation of v1 coming in future release</li>
 <li>Lots of new  <a href="http://aurora.apache.org/documentation/0.6.0-incubating/">documentation</a>. Documentation now includes pages for <a href="http://aurora.apache.org/documentation/0.6.0-incubating/deploying-aurora-scheduler/">deploying the Aurora scheduler</a>, <a href="http://aurora.apache.org/documentation/0.6.0-incubating/cron-jobs/">cron jobs</a>, <a href="http://aurora.apache.org/documentation/0.6.0-incubating/sla/">SLA measurement</a>, <a href="http://aurora.apache.org/documentation/0.6.0-incubating/storage/">storage</a>, and <a href="http://aurora.apache.org/documentation/0.6.0-incubating/storage-config/">storage configuration and measurement</a>.</li>
 </ul>

 <p>Full release notes are available in the release <a href="https://gitbox.apache.org/repos/asf?p=aurora.git&amp;f=CHANGELOG&amp;hb=refs/tags/rel/0.6.0-incubating">CHANGELOG</a>.</p>

 <h2 id="highly-available-scheduler-driven-updates">Highly-available, scheduler-driven updates</h2>

 <p>Rolling updates of services is a crucial feature in Aurora. As such, we
 want to take great care when changing its behavior. Previously, Aurora operated
 by delegating this functionality to the client (or any API client, for that
 matter). In this version, the scheduler can take over the
 responsibility of application update orchestration. Further details were discussed on the <a href="http://mail-archives.apache.org/mod_mbox/aurora-dev/201407.mbox/%3CCAGRA8uMxwVDokp_iHXhNru2gd-x_nM%2BDYAurpfAO6wuX7%3DnHFw%40mail.gmail.com%3E">Aurora mailing list</a>.</p>

 <h2 id="aurora-web-ui-improvements">Aurora Web UI Improvements</h2>

 <p>Since the scheduler can now orchestrate job updates, it has awareness of the progress and outcome of updates.  This means you can see a progress bar for in-flight updates, and the history of updates for your jobs.  Additionally, the performance of the UI was improved, especially for large roles and jobs <a href="https://issues.apache.org/jira/browse/AURORA-458">AURORA-458</a>.</p>

 <h2 id="service-announcement-and-management">Service Announcement and Management</h2>

 <p>Job configurations can now supply an <a href="http://aurora.apache.org/documentation/0.6.0-incubating/configuration-reference/#announcer-objects"><code>announce</code> parameter</a>, which is meant to be a way to opt-in for registration in a service discovery system. This has been implemented in the Aurora executor, and will automatically announce tasks via ZooKeeper.</p>

 <h2 id="aurora-client-improvements">Aurora Client Improvements</h2>

 <p>Progress was made in features to v2 of the <a href="http://aurora.apache.org/documentation/0.6.0-incubating/client-commands/">Aurora client</a>. We will support version 1 and version 2 for 0.6.0, with version 1 to be removed in 0.7.0.</p>

 <h2 id="improved-project-documentation">Improved Project Documentation</h2>

 <p>New documentation pages including:</p>
